w. Raes', of

Be it known that we, HENRY Cincinnati, in the county of Hamilton, in i the State of Ohio, and Earn. R.- BELL, of Covington, in the county of Kenton, in the State of Kentucky, have invented certain new and useful- Improvements in Adjustable Shores; and we' do hereby declare' the following to be a full, clear, andexact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the referencevnumerals marked thereon.A

Our invention relates to adjustable shores for use in connection with concrete structures and the like, the purpose being-to provide a. simply constructed device that can be economically made for supportin concrete forms, such as girder, beam an 'floor forms, until the composition. material within the forms has thoroughly dried and hardened, andv for any other purpose where sharing isnecessary. y

A further purpose of the invention is to Pprovide a device that is readily adjustable as to size in order tosupport forms at different elevations, and which, when-adjusted,

will support the load firmly, the parts being so arranged that the gripping action of the adjustable parte, one upon the other, increases in proportion to the load put upon the device.

To these. and other ends the invention consists in certain improvements and combina.- tions of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

'In the drawings: Figure 1 is a front elevation of a construction showing a preferred embodiment othe invention; Fig. 2,' is a l f side view, and Fig. 3 is a horizontal section on the line fik-3 of Fig. 1

Similar reference share., ers'in the several figures indicate the same-parts,

According to the present embodiment, which illustrates a preferred method of carrying out the inventien, we employ a pair of relatively movable members, which can be adjusted with relation to each other and securely retained in such adjusted relation, the lower member resting upon s. floor or other support while the upper member engages the form orstructure to be supported.

The lower member preferably comprises a post A adapted to rest upon the floor, as shown inI Figs. 1 and 2. The post A is provided withan enlarged, upper end, which may beformed by seourm blocks B to the opposite sides thereof. designates strips or barswhich vare suitably secured to opposite sides of the member A, and extend beyond the blocks QB, forming recesses or guideways for the upper member, which is now to be described. f

The upper-member includes-a horizontal or supporting portion D, to which areconnected vertical portions or legsl E, the latter being held in proper relation to the horizontal portion by means of the attaching straps F. The legs E are adapted to engage the blocks B of the lower member, being movablebetween the end portions of the strips C, which thereby serve as centering guides to retain the upper 4member in its'proper relation to the lower member.

The relatively movable members are held in ltheir vadjusted relation by means of i clamping devices carried by the legs E, andY engaging the post A. To thisend, we employ a pair of clampin yokes, one pivoted upon each leg E, the yo `'e being designated at G. The clamping yok are also pivotally connected to eachother-Mld, and include clamping portions djff'jjaws I which engage opposite sides of tlfeepost A in the manner shown in Figs. 1 3.I The clamp ing yokesare preferably ofequal size and are attached, as shown in Fig. 3, a spacing block orv washer J being employedsbetween the legs E and the adjacent walls of the will be the gripping action of the clamping yokes, Yso that the parts are securely retained in their adjusted relation as long ,as any application of pressure continues. Y

We claim as our invention:

1. An adjustable shore comprising a pair of relatively movable' members, and a pair of clamping yokes pivoted to one of said members, said yokes being pivotally connected to each other and having engagement with opposite sides of 'the other of 'said members.

2., An adjustable shore comprising a lower sides lof the post.

member in the form of a post, an upper member movable relatively t0 the Alower member and including a pai-r of legs arranged on opposite sides of said post, and e clamping yoke pivoted to each of said legs, the clamping yokes being pivotelly connected to eachother and .engaging opposite HENRY W.
